connection timeout

Posted By:Posted Date:April 14, 2011Points:0Category :

My method executes lots of asynchronous SQL requests and I constantly get connection timeout exceptions. What else can
I do except increasing the connection timeout value and proper indexing? I mean with the database part, not with the code part. Can't change the code part. Besides, the application is running fine on different servers, but only I experience those timeout exceptions
on my pc and local MS SQL Server 2008 R2 database (which is also on the same PC). So I think this is clearly a performance issue since the connection timeout is already set to 3 minutes. Maybe there is something I can change on the server? Maybe there is a
number of simultanious requests constraint? Each of my requests needs clearly less that 3 minutes, but there are about 26 000 of them running asynchroniously, and only I experience those problems on my local PC and local DB.

Client: Sql Sever Management Studio Express 2005 (SSMSE) on Vista
Server: Sql Server 2005 Express on Windows Server 2008 Standard
When I first try to log into SSMSE from the client machine, the login operation times out. When I retry, the login succeeds almost immediately. If I close the app and re-open it, the same thing happens. This appears to be infinitely repeatable. I am able
to reproduce this behavior using SQLCMD.exe. Here's the error:
"Timeout expired. The timeout elapsed prior to completion of the operation or the server is not responding. (Microsoft SQL Server)"
The technical details reference Error Number -2
What may be unique or tricky about this client's network is that it's a mixture of IPv4 and IPv6. I believe the server is configured for both, but honestly the networking side of things is outside of my expertise.
Has anyone else experienced a problem like this? I'm looking for some troubleshooting tips and of course a flat-out answer :-).
Thank you in advance for your time and expertise - I hope I've broken the problem down to its simplest form.
Will.

How do you modify the default 15 second timeout Connection Timeout on SQL databases in SQL 2005, for all users? I am able to modify the value on an individual basis through the options menu on the SQL Server 2005 login window however when signing on as
a different user the changes do not carry to that users profile.

Periodically (~ once per 15 min) some db-clients have error messages when open connection (over SQL Native Client ) like:

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

All timeouts more or equal 15 sec. Less then 15 sec is not acceptable by business rules. Performance counters (cpu,memory,disk etc.) on server does not show bottleneck. Only one sql counter - logins/sec show trouble. When problem exists then this counter
= 0. Also dramatically decrease many other counters - sql batch requests/sec, transactions/sec, cpu load and some ones. SQL Server "sleep" few seconds (4 - 5) and then accessible again.

Hello everyoneI'm checking these parameters to connect to a server from a wireless client in the presence of little or no coverage to alert the operator of the problem.I tried to lower both the timeout to 5 seconds. But if there is no connection sometimes takes 90 sec. sometimes only 45sec. first to tell me that is not 'unable to contact the server.The connection string I use is' this:Provider = SQLOLEDB.1; Persist Security Info = False; User ID = sa; Initial Catalog = Ideabiella; Data Source = localhost; Connect Timeout = 5;and when I open the command also sets the CommandTimeout to 5sec.where am I wrong?

hello,i have a problem ,when i connect to a sqlserver database,if the machine has closed,or the machine have not a sqlserver service,my progrem will block about 30s,it's too long,so i change the connection string like that

I have started getting this error since a week now when I try to schedule a report or change a schedule of a report.

An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError) Get Online Help For more information about this error navigate to the report
server on the local server machine, or enable remote errors

We have SQL Server 2008 installed along with SSRS running on the server. I have never seen this happening before for almost a year now but suddenly it appeared. Along with this, report subscription is also messed up and some report are not been
emailed as they have a error like:

Failure sending mail: An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database.Mail will not be resent.

I am not sure what caused this but if anyone has any idea of what is going on it will be great.

I have one webservice . previously i had used microsoft enterprice library then i got some tome out exception then some of my friends told that the exception because of enterprice library . then i changed my data access layer to normal connection.

But still i got the time out error ... also i had done some more settings

ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.

EncapsulationLet's abstract away the source of the connection string using a class with a static property.

I keep getting the following error. I also added time out parameter in the connection stirng and it still did not help. Has any one faced similar issues.

Thanks in adavance.
